After a heavy autumn rainstorm, Leo watches large puddles form on the playground. Over the next three warm days under the sun, the water level slowly drops until the pavement is completely dry.

Evaporation

200

This process involves carefully recording what you see, notice, or measure during an experiment.

An observation
200

The temperature that my pot of water will begin to boil at.

100 degrees celsius - boiling point.

300

This state of matter has no fixed shape, can flow, and takes the shape of its container.

Liquid

300

Is the following a form of matter? If so, is it a solid, liquid or gas?

- A shadow

Not a form of matter.

Daniel steps inside the school during a cold December morning and within a couple of seconds a thick layer of tiny water droplets fogs up and coats his pair of glasses.

Condensation

300

During the ice cream lab, this substance was added to the ice to lower the freezing point of water.

Salt

300

Draw the particles of a gas.

- Wild and free, lots of space, movement (arrows).

400

Every solid, liquid and gas is made up of these tiny particles that can only be seen with a very strong microscope.

Atoms

Is the following a form of matter? If so, is it a solid, liquid or gas?

- Toothpaste

- Acceptable answers: Solid, liquid, or non-newtonian fluid.

Mr. MacGregor loves all things spooky! To celebrate Halloween he decides to go to all the haunted houses he can find. One in particular was especially scary; the whole house was covered in a thick white fog that made everything hard to see.

Sublimation.

400

During the ice cream lab, this type of energy moves out of the liquid cream mixture and into the cold ice-and-salt mixture.

Thermal energy (or heat).
400

Dry ice is extremely cold and undergoes sublimation at this exact temperature on Earth.

-78.5 degrees celsius.

500
Matter is anything that has 1. ____ and 2._____.

Mass (or weight) and volume (or takes up space).

500

Heat, sound waves and electricity are NOT examples of matter. What are these actually examples of?

Energy.

Mrs. Gohl looks out the window one crisp November morning. She notices a shimmering white blanker of delicate ice crystals covering the grass.

Deposition

500

Why did we shake the bag during the ice cream experiment?

  • Fast Freezing: Shaking keeps the inner bag touching the super-cold ice and salt mixture so heat leaves the cream quickly.
  • Smooth Texture: Constant motion breaks up large ice crystals as they form, which gives you soft-serve style ice cream.
  • Air Incorporation: Shaking pushes tiny air bubbles into the cream to make it light and fluffy.

In Canada, frost is more likely to form on the ground in the fall rather than the winter. Why do you think this is?

Frost is more likely to form in the fall because there is still warm, moist air from the daytime during the fall compared to the daytime temperature in the winter.
